The Long Run

I am training for my second ultra and am doing it with a newborn and a 2-year old. Any thoughts on breaking up a long run, 20 - 35 miles, into perhaps three runs throughout the day? Thanks!

I trained for my first ultra pushing my 18 month old in a stroller for about 75% of all my runs. They lasted about as long as he could (13 miles or so), so i would often do two a days of this distance.

You will gain a lot of fitness by doing this, because you can run faster for each leg rather than death marching for 35 miles.

I only did two long runs past 30 miles, at 8 and 4 weeks prior to the race. I planned these special, and had family on hand to watch my son while i spent most of the day getting to and running around in the woods.

I realize this is way late response to your post, but hope it helps.
